The two shafts $$AB$$ and $$BC$$, of equal length and diameters $$d$$ and $$2d$$, are made of the same material. They are joined at $$B$$ through a shaft coupling, while the ends $$A$$ and $$C$$ are built-in (cantilevered). A twisting moment $$T$$ is applied to the coupling. If $${T_A}$$ and $${T_C}$$ represent the twisting moments at the ends $$A$$ and $$C,$$ respectively, then A
$${T_c} = {T_A}$$
B
$${T_c} = 8{T_A}$$
C
$${T_c} = 16{T_A}$$
D
$${T_A} = 16{T_C}$$
